How paul fisher changes throughout the text.

The main change he goes through is finding his identity in the shadow of his older brother, Erik. He also finds the courage to confront Erik at the end of the novel, which no one else in his life has been able to do. Paul is dealing with a move from Houston, Texas to Florida

It seems that you have missed the given options for this question. But anyway, here is the correct answer. The excerpt from Everyday Use by Alice Walker that employs the technique of ambiguity would be this: 
Dee wanted nice things. A yellow organdy dress to wear to her graduation from high school; black pumps to match a green suit she'd made from an old suit somebody gave me. She was determined to stare down any disaster in her efforts.
Hope this answer helps.
